摘　　要：为了探讨湘南浓香型特色优质烟叶植烟区长期施用硫酸钾肥对"烟-稻"轮作制植下烟叶的生长和产质量的影响,2011年在桂阳开展了不同硫施用量对烟叶产质量影响的研究。结果表明:不同施硫量下,烟叶田间长势长相,农艺性状,烟草的生育期,烟株抗逆性,烟叶外观质量及烟叶产值、烟叶均价、上中等烟比例等各个考核指标均无显著性差异,但以T4(硫酸钾1 200 kg/hm2)表现最好,不施硫的对照最差。因此,在桂阳"烟-稻"轮作的前提条件下,增加施用硫酸钾肥仍不失为提高烟叶质量和烟叶含钾量的可行措施。In 2011, in order to study the influence of the long-term application of sulfuric acid potassium on yield and quality of tobacco leaves in Luzhou-flavor tobacco planted zone in southern Hunan with the ＂tobacco-rice＂ rotating system, the test of different applying amounts of sulfur on yield and quality of tobacco leaves was carried in Guiyang county. The results showed that there were not any significant difference in each test index among all of the treatments, such as growth potential of tobacco in field, agricultural traits, growth period of tobacco, appearance quality, yield, quality, mean output value and ratio of superior-middle tobacco. But, all determination indexes in T4 treatment （applying 1 200 kg/hm2 of sulfuric acid potassium） were the best, and those in control without applied any sulfuric acid potassium were the worst. Therefore, with the ＂tobacco-rice＂ rotating system in Guiyang County, adding application of sulfuric acid potassium is a feasible measure to improve quality of tobacco and increase potassium content in tobacco leaves.
